在世界闻名的英国西敏寺大教堂地下室的墓碑林中，有一块扬名世界的墓碑。墓碑上刻着这样的话： 

"When I was young and free and my imagination had no limits, I dreamed of changing the world. As I grew older and wiser, I discovered the world would not change, so I shortened my sights somewhat and decided to change only my country.  But it, too, seemed immovable.  As I grew into my twilight years, in one last desperate attempt, I settled for changing only my family, those closest to me, but alas, they would have none of it.  And now as I lie on my deathbed. I suddenly realize: If I had only changed myself first, then by example I would have changed my family. From their inspiration and encouragement, I would then have been able to better my country and, who knows, I may have even changed the world. "
